Abstract目的:观察应用经伤椎椎弓根螺钉技术治疗单椎体胸腰椎骨折的临床疗效。 方法:回顾性分析我科于2013年1月-2014年6月收治的单节段胸腰椎骨折病人23例,损伤节段为T11-L2,年龄26-59岁,平均年龄47.8岁,所有患者均在受伤后10天内接受后路伤椎椎弓根螺钉和相邻上下椎椎弓根螺钉6枚螺钉内固定术治疗,观察术后疗效,包括术后短期并发症,椎体前缘高度比值及后凸Cobb角,以及脊髓神经功能损伤恢复情况,并进行统计学分析。 结果:23例患者随访4-15个月,随访平均时间为8.5个月,所有病例术后短期内(4-15个月)均未出现严重并发症;末次随访未出现钉棒断裂及内固定松动等情况;术后及末次随访所测得椎体前缘高度比值均较术前明显改善,差异有统计学意义(P<0.05);术后及末次随访后凸Cobb角较术前明显改善,差异有统计学意义(P<0.05);两项指标末次随访较术后相比稍有反弹,但差异无统计学意义(P>0.05);大部分患者脊髓神经功能有所恢复。 结论:经伤椎椎弓根螺钉内固定术治疗单节段胸腰椎骨折,能够有效恢复伤椎高度及矫正后凸畸形,并能保持矫正效果,钉棒断裂发生率低,是一种治疗单节段胸腰椎骨折安全、有效的术式。 关键词:胸腰椎骨折,伤椎,椎弓根螺钉,Cobb角
Other AbstractObjective: To evaluate the clinical efficacy of pedicle screw fixation through the pedicle of fractured vertebra in the treatment of the thoracolumbar fractures of single segment. Methods: A total of 23 patients with thoracolumbar fractures treated at our department between January 2013 and June 2014 were retrospectively studied. The fractured vertebral is between T11 to L2, the patient’s age is between 26 to 59 years old, The average age is 47.8 years old, all the patients received the Surgery operation on within 10 days, which is implantation of pedicle-screws both in fractured vertebra and its upper and lower vertebra. To observe the efficacy, include Short-term postoperative complications, the ratio of Vertebral height and Cobb angle, the Recovery of neurological function, this data were statistically analyzed. Results: 23 cases were followed up for 4 to 15 months, the average time is 8.5 months, All patients were not severe complications in the short term (4 to 15 months) , there were not Pedicle screw breakage and Internal fixation loosening at Last follow-up, the vertebral height ratios which were measured in postoperative and final follow-up is significantly improved compared with Preoperative, The difference were statistically significant (p<0.05) , the Cobb angles which were measured in postoperative and final follow-up is significantly improved compared with Preoperative, The difference were statistically significant (p<0.05) , Two indicators of last follow-up are slight rebound than postoperative, but the difference were not statistically significant (p>0.05) , the Neurological function of most patients were Partially recovery. Conclusion: The pedicle screw fixation through fractured vertebra is effective in the treatment of the thoracolumbar fractures of single segment, it Can effectively restore vertebral height and correct Kyphosis, and Maintain correction effect, it is low incidence of screw rod fracture, it is safe and effective method to the thoracolumbar fractures. Key words: Thoracolumbar fractures, Fractured vertebrae, Pedicle Screw, Cobb angle
